100% RENEWABLES – Making a Reality –

THE CONCEPT

Thusitha Sugathapala

Senior Lecturer

Department of Mechanical Engineering

University of Moratuwa

Stable population of around 23 million people, transformed to energy conscious society

Developed, knowledge based economy18000MW demand Lowered to 15,000MW due to low energy intensity of economy Further lowered by EE gains to 10,000MW ( 10 kWh/person/day)

A transformed society With full digital convergence Integrated mostly electronically

OVERALL APPROACH

2

Electricity system Taken over the most aspects of the energy industry through an

Internet Protocol (IP) based smart grid Powered, mostly by centralized wind parks and distributed solar PV,

assisted by storage hydro Biomass, agro and municipal waste streams supporting firm power EV batteries & pumped storage developed to support the RE fed grid Hence size of the grid increased to 25,000MW

Complete electrification of transport realized Most major cities will be predominantly pedestrian in character and

will have only electric bicycles, scooters, E3Ws and E-taxis to support Passenger transport dominated by electric trains and electric BRT

supported by a fleet of EV taxis Storage capacity of EVs used as a grid balancer Hydrogen Fuel cell vehicles, Compressed air vehicles Algae based biofuels and compressed biogas powering long haul

transport
